Technical Field
The invention relates to the technical field of automobiles, in particular to a display screen brightness control method, a device and equipment and an automobile.
Background
The existing method for adjusting the brightness of the vehicle-mounted display screen mainly comprises two modes of manual adjustment and automatic adjustment, wherein the screen brightness can be adjusted according to the needs through manual adjustment, but when the ambient light brightness changes, the screen brightness needs to be manually adjusted again. The lower-level mode in the automatic adjustment is to set a daytime mode and a night mode, and the brightness of the display screen is adjusted according to the opening state of the light of the vehicle, so that the brightness of the daytime mode and the night mode can be adjusted only. A more advanced method in automatic adjustment is to add an ambient light sensor, set different brightness levels, and adjust the brightness of the display screen according to the ambient light level detected by the ambient light sensor.
In the automatic adjustment, different drivers (e.g., old, young, myope, astigmatic) use the same automatic brightness adjustment level, and the brightness cannot be adjusted according to the needs of each person because the screen brightness to which each person is adapted is different at the same ambient light level. Because the brightness level cannot adapt to the requirement of the driver on the screen brightness, the long-time driving can lead to visual fatigue of the driver, or when the brightness of the environment is changed, the brightness of the display screen is seriously deviated from the requirement of the driver on the screen brightness, so that the safety problem is caused. And the brightness will decrease along with the increase of the service time of the display screen, at this time, the ambient light brightness level and the display screen brightness level will change, the corresponding relationship between the two will fail, if the meaning of the automatic adjusting function will be lost without correction.
